[0034] In order to realize artificial ice making, the refrigerating device 8 is arranged on the bottom plate 6, the refrigerating device 8 is connected with the cooling pipe 9, one end of the cooling pipe 9 is connected with the cold air outlet of the refrigerating device 8, the other end is connected with the return flow port of the refrigerating device 8, the return flow port is connected with the air inlet of the refrigerating device 8, the cooling pipe 9 is a tapered spiral pipe, and the bottom plate 6 is provided with the cold pipe frame 10 for supporting the cooling pipe 9. If it is required to improve the refrigeration efficiency, the return flow structure of the cooling pipe 9 can be cancelled, and a nozzle facing the pit 2 is arranged on the side wall of the cooling pipe 9, so that the cold air is directly sprayed on the bottom surface of the pit 2. In order to reduce heat loss, the machine shell 1 is arranged on the bottom plate 6 to cover the structure below the pit 2, but in order to meet the swinging requirement of the pit 2, a gap is required between the pit 2 and the machine shell 1. Considering the problem of condensed water in the air in the machine shell 1, the protective shell is arranged on the motor 11 and the speed reducer 12 for waterproof and moisture-proof, the drainage port is arranged on the machine shell 1, and the bottom plate 6 is inclined to the drainage port. In order to ensure the smoothness of the air duct of the refrigerating device 8, the ventilation hole is arranged on the machine shell 1 opposite to the refrigerating device 8, and the drainage port and the ventilation hole are both communicated with the outside. In order to uniformly distribute water on the upper surface of the pit 2 to make the ice surface more uniform, the annular spray pipe 3 is arranged above the pit 2, the spray pipe 3 is connected with the machine shell 1 through the spray pipe frame 4 to form a support, the spray pipe 3 is connected with the water inlet pipe 5 and is provided with the nozzle facing the inner wall of the pit 2. The water inlet pipe 5 is connected with the water supply device, which can be a municipal water supply pipe or a water tank 23, the water pump 24 is arranged in the water tank 23, the outlet of the water pump 24 is connected with the water inlet pipe 5, and the water pump 24 and the water tank 23 are adopted for water supply in the embodiment.

[0035] Further, it further includes a platform 21, such as Figure 8As shown, the platform 21 has a circular hole for accommodating the entertainment structure, the top surface of the platform 21 is close to the upper edge of the pit body 2, but there is a space for the pit body 2 to swing between the platform 21 and the pit body 2, the drain outlet passes through the drain pipe out of the platform 21, the platform 21 is a frame structure with a flat plate on top, and the platform 21 has a through hole for the ventilation hole to communicate with the outside. In order to improve safety, a protective fence is arranged on the platform 21 (not shown in the figure). One side of the platform 21 has a ladder, and the challenger can climb onto the platform 21 through the ladder.

[0036] In order to facilitate control, a control device is also arranged, the control device has an STM32 processor, and an external touch operation screen, a temperature sensor is arranged in the shell 1, and a flow sensor and an electromagnetic flow valve are arranged on the water inlet pipe 5, as shown in the figure. Figure 12 As shown, the STM32 processor and the temperature sensor, the touch operation screen, the refrigerator 8, the motor 11, the water pump 24, the flow sensor and the electromagnetic flow valve are electrically connected, and the current temperature can be displayed on the touch operation screen.

[0037] The working principle of the utility model:

[0038] After the staff sets the refrigeration temperature on the touch operation screen, the STM32 processor starts the motor 11, the motor 11 starts to run, is reduced after gear reducing machine 12, drive gear 13 rotates, gear 13 drive gear ring 14 drives pressure bar 15 to rotate, pressure bar 15 is pressed in the rotation process one by one the pressure surface of suspender 17, so that the pit body 2 is inclined, and the inclined suspender 17 on one side presses the corresponding spring 22, and when the spring 22 is compressed to the maximum, the maximum deflection angle of the pit body 2 is obtained, and the maximum deflection angle of the pit body 2 is 2 degrees.

[0039] After the processor detects that the temperature in the shell 1 reaches the set temperature (-15 DEG C) through the temperature sensor, the electromagnetic flow valve is opened, and the water pump 24 is started, and water is supplied according to the set flow, and the water enters the spray pipe 3 through the water inlet pipe 5, and then is sprayed on the inner wall of the pit body 2 through the spray port. Because the temperature of the pit body 2 is low, the water freezes during the flow process on the surface of the pit body 2 or freezes after gathering at the bottom of the pit body 2.

[0040] After the processor detects that the water supply reaches the set amount through the flow sensor, the operation of the water pump 24 is stopped, and the electromagnetic flow valve is closed, and the motor 11 stops running.

[0041] After staff confirms that the ice layer inside pit 2 is frozen solid, challengers, guided by staff, put on protective gear and ascend the stairs to platform 21 before entering pit 2 to begin the ice pit challenge. At this point, due to the downward pressure of lever 15 on hanging rod 17, the spring 22 opposite lever 15 is compressed to its maximum extent, and the deflection angle of pit 2 is fixed. To increase the difficulty and fun, staff can operate the control panel to start motor 11, causing pit 2 to deflect. The rotation speed of the toothed ring 14 is 5 cm / s.

[0042] Once the challenger reaches platform 21 or abandons the challenge, the staff will stop motor 11 from running via the control panel. Example 2

[0043] like Figure 9 As shown, the difference between this embodiment and Embodiment 1 is that the refrigeration mechanism uses an outdoor air conditioning unit, which is located outside the casing 1. Inside the casing 1 is a blower, and inside the blower casing are an evaporator and a fan. The evaporator is connected to the outdoor air conditioning unit. The blower casing has an air inlet and an air outlet, located on both sides of the evaporator. One side of the blower faces the air inlet, and the other side faces the evaporator. The blower draws in air from the air inlet and blows it towards the air outlet. During this blowing process, the air is cooled by passing through the evaporator. This process is similar to that of an indoor air conditioning unit, but the outer casing structure is different. The cooling pipe 9 is connected to the air outlet hose of the blower casing, and the cooling pipe 9 is welded to the bottom of the pit 2. Figure 13 As shown, both the outdoor chiller and the blower are electrically connected to the STM32 processor. The method of electrical connection between the outdoor chiller and the STM32 can be inspired by the existing electrical connection method of air conditioners and is considered prior art.

[0044] The water distribution mechanism uses a rotating nozzle 25, which is connected to the outlet of the water pump 24 in the water tank 23. The water distribution mechanism is mounted on a movable trolley.

[0045] When ice making is needed, the staff first sets the cooling temperature (-15℃) using the touch screen. The processor starts the outdoor air conditioning unit and blows the cold air generated by the evaporator into the cooling pipe 9 to cool the pit 2. After the staff observes that the temperature of the pit 2 has reached -15℃ through the touch screen, they move the water distribution mechanism to the side of the ice pit entertainment structure and start the water pump 24 using the touch screen. The water pump 24 sends the water in the water tank 23 into the rotating nozzle 25 and sprays it out. The rotating nozzle 25 rotates and sprays water from the top of the pit 2 into the pit 2. Because the temperature of the pit 2 is low, the water gradually freezes in the pit 2, thus making ice on the pit 2. Example 3

[0046] like Figure 10As shown, the difference between this embodiment and embodiment 2 is that the cooling pipe 9 is no longer provided. Instead, an indoor air conditioner cooler is installed inside the casing 1. The indoor air conditioner cooler is connected to the outdoor air conditioner to form an air conditioning system. The indoor air conditioner cooler blows air directly into the casing 1 for cooling. Figure 14 As shown, the control device also includes an infrared signal transmitter, which is electrically connected to the STM32 processor. The infrared signal of the infrared signal transmitter is matched with the infrared signal receiver of the indoor air cooler, and the infrared signal transmitter is opposite to the indoor air cooler. Example 4

[0047] like Figure 11 As shown, the difference between this embodiment and Embodiment 3 is that the ice pit entertainment structure is located indoors, the outdoor air conditioning unit is located outdoors, and the indoor air conditioning fan is located indoors. The casing 1 is omitted, and the indoor air conditioning fan directly blows cold air into the room where the ice pit entertainment structure is located, cooling the entire room. The indoor air conditioning fan and the outdoor air conditioning unit are electrically connected to the STM32 processor. Example 5

[0048] The difference between this embodiment and Embodiment 2 is that the water distribution mechanism adopts a water injection mechanism, the outlet of water pump 24 is connected to a water injection pipe, and it also includes a water pump and a water pumping pipe. The inlet of the water pump is connected to the water pumping pipe, and the outlet of the water pump is connected to the water tank 23. Figure 15 As shown, the water pump is electrically connected to the STM32 processor. When ice making is needed, the pit 2 is first cooled down. After the temperature reaches the set temperature on the touch screen, the operator pours water into the pit 2 using a water injection hose. Once the desired liquid level is reached, the water injection stops, and the operator waits 5 minutes for the water in the pit 2 to freeze. Because the temperature of the pit 2 is lower than the ambient temperature, the water in contact with the pit 2 freezes before the surface. After the ice layer reaches the desired thickness, the operator places the water injection hose into the pit 2 and starts the water pump using the touch screen to pump the remaining water in the pit 2 back to the water tank 23. After completion, the water pump is turned off. Once the ice layer in the pit 2 is confirmed to be solid, the ice pit challenge continues. Example 6

[0049] The difference between this embodiment and embodiment 1 is that the cooling pipe 9 is used as the evaporator of the refrigerator 8 and connected to the refrigerant circulation pipeline in the refrigerator 8. During the refrigeration process of the refrigerator 8, the boiling point of the liquid refrigerant is below -30°C. After entering the cooling pipe 9, it will evaporate into a gaseous state in the cooling pipe 9. During this process, it absorbs a large amount of heat from below the pit 2, which cools down the pit 2. The gaseous refrigerant flows back to the refrigerator 8 and enters the refrigerant circulation pipeline for circulation. Example 7

[0050] The embodiment is different from that of the embodiment 1 in that the swing mechanism is cancelled, the pit body 2 is directly fixedly connected on the support 7, and in the use process, the swing of the pit body cannot be performed any more, and the staff only needs to control the water distribution mechanism to directly guide the challenger to wear the protective gear and then to enter the pit body 2 through the platform 21 after ice is made in the pit body 2.

[0051] The circuit and mechanical connection involved in the utility model are the common means adopted by the person skilled in the art, and the technical inspiration can be obtained through limited tests, and belong to the public common knowledge.

[0052] The components not described in detail in the present application are the prior art.

[0053] Although the embodiments of the utility model have been shown and described, it can be understood by those of ordinary skill in the art that various changes, modifications, replacements and variations can be made to the embodiments without departing from the principles and spirits of the utility model, and the scope of the utility model is defined by the appended claims and their equivalents.
